The Open-OS Index
The Freedom Index
for Operating Systems.
A public ranking that certifies how well each operating system respects user sovereignty, neutrality and general-purpose computing. Every grade follows a public rubric, with cited evidence and full history.
How it works
Each operating system is scored 0–100 on seven weighted dimensions. The overall score is a weighted average that maps to a grade from S (Absolute Sovereignty) down to F (Hostile).
The rubric is public and versioned. Every score links to evidence. Anyone can challenge a verdict by opening an issue or a pull request.
